Abstract (en)
A composite metal/plastic patellar prosthesis for implantation in the human body to replace the articulating surface of the patella is provided. The prosthesis includes a polymeric articulating surface portion (15) and a metal backing (12) having an anterior surface adapted to be attached to the posterior surface of a resected patella and a dome or conically shaped posterior surface to which the polymeric articulating surface portion is heat and pressure molded. The metal backing portion has at least one aperture (16) extending therethrough which has a greater cross-sectional area on the anterior side than on the posterior side into which an anchoring peg integral with the anterior surface of the polymeric articulating surface portion is molded. The metal and plastic components of the composite are coextensive in size and shape. <IMAGE>
